    Background: COVID-19 has a significant impact on the hematopoietic system and hemostasis. Leukocytosis, lymphopenia, and thrombocytopenia are associated with increased severity and even death in COVID-19 cases. Objective: The aim is to examine the laboratory results of COVID-19 patients from a hospital in the Peruvian Amazon and their clinical prognosis. Material and Methods: An analytical cross-sectional study was carried out whose purpose was to identify the laboratory tests of patients with COVID-19 and mortality in a hospital in Ucayali, Peru during the period from March 13 to May 9, 2020, selecting a total of 127 with Covid-19. Mean and the standard deviation was described for age, leukocytes, neutrophils, platelets, RDW-SD; median and interquartile range for the variables lymphocyte, RN / L, fibrinogen, CRP, D-dimer, DHL, hematocrit, monocytes, eosinophils. Results: No differences were observed in this population regarding death and sex (OR: 1.31; 95% CI 0.92 to 1.87), however, it was observed that, for each one-year increase, the probability of death increased by 4% (PR: 1.04, 95% CI 1.03 to 1.05). The IRR (Incidence Risk Ratio) analysis for the numerical variables showed results strongly associated with hematological values such as Leukocytes (scaled by 2500 units) (IRR: 1.08, 95% CI 1.03 to 1.13), neutrophils (scaled by 2500 units) (IRR: 1.08; 95% CI 1.03 to 1.13), on the contrary, it is observed that the increase of 1000 units in lymphocytes, the probability of dying decreased by 48% (IRR: 0.52; 95% CI 0.38 to 071). Conclusions: Parameters such as leukocytes,neutrophils and D-dimer were statistically much higher in patients who died.

    Objective: The new coronavirus pandemic (COVID-19) has spread to 180 countries, causing more than half a million confirmed cases and more than 40 thousand deaths. The main objective of this study was to analyze the world scientific production related to COVID-19. Material and Method: A literature search was performed using the Scopus database. A total of 547 published documents were identified, analyzing characteristics such as: type of publication, collaboration index, most productive countries, scientific journals, the institutions that are publishing the most on the subject and indicators of citations and impact. Results: China was ranked first with 213 published documents (20.9%). Regarding the journals with the higher number of published documents, these were The Lancet, British Medical Journal and the Journal of Medical Virology. Likewise, Wuhan University was identified as the institution presenting the highest leadership regarding the number of publications. The total number of citations for all the publications was of 1.685. The h-index of the retrieved articles was of 42, and four articles were found with more than 100 quotations. Conclusions: This study offers a first approach to the global efforts aimed to this new area of research, which in only three months has substantially increased, and is expected to remain being prolific.
